Introduction

Why does Citta perceive something correctly at one moment, misunderstand it at another, construct an idea through words, enter sleep, and later retain or recall a previous experience?

The Yoga Sūtras of Patañjali present a remarkably precise Yogic classification of these activities of Citta.

These activities are called Vṛttis.

In the Samādhi Pāda, Patañjali defines Yoga in relation to Citta and its Vṛttis:

योगश्चित्तवृत्तिनिरोधः॥१.२॥

Yogaś citta-vṛtti-nirodhaḥ

He then explains that the Vṛttis are fivefold and may be either Kliṣṭa—afflictive—or Akliṣṭa—non-afflictive.

Understanding the Pañca Vṛttis, or five modifications of Citta, is essential for understanding both the philosophical psychology and the practical discipline of Pātañjala Yoga.

The purpose is not simply to label every thought as an enemy.

Nor is the teaching merely telling us to “stop thinking.”

The deeper issue concerns the activities of Citta, the apparent identification of the Seer with these modifications, and the Yogic movement towards Nirodha.

To understand this carefully, we must first return to Patañjali's definition of Yoga.

Yoga and Citta-Vṛtti-Nirodha

Patañjali states:

योगश्चित्तवृत्तिनिरोधः॥१.२॥

Yogaś citta-vṛtti-nirodhaḥ

Word-by-Word Meaning

• Yoga (योग) — Yoga; the discipline and state described within the Pātañjala system
• Citta (चित्त) — The inner cognitive apparatus or mind-field; a technical term that should not be reduced without qualification to the ordinary English word “mind”
• Vṛtti (वृत्ति) — Modification, activity, operation, mode, or functional movement of Citta
• Nirodha (निरोध) — Restraint, stilling, cessation, or restriction of the Vṛttis; a technical Yogic term whose full significance develops throughout the text

Concise Translation

“Yoga is the stilling of the modifications of Citta.”

The next two sūtras are essential for understanding why this matters.

तदा द्रष्टुः स्वरूपेऽवस्थानम्॥१.३॥

Tadā draṣṭuḥ svarūpe 'vasthānam

“Then the Seer abides in its own nature.”

Patañjali continues:

वृत्तिसारूप्यमितरत्र॥१.४॥

Vṛtti-sārūpyam itaratra

“At other times, there is conformity with the Vṛttis.”

These sūtras establish the philosophical context for the discussion that follows.

The problem is not merely that “the mind thinks too much.”

The issue is more fundamental.

Within the Pātañjala framework, the Draṣṭā—the Seer—is distinct from the changing activities presented in Citta . Yet, outside the state described in Yoga Sūtra 1.3, there is sārūpya—a kind of conformity or apparent identification with the Vṛttis.

This should not be reduced only to the modern psychological idea of “being identified with thoughts.”

The distinction is metaphysical as well as practical.

A thought arises, and practically we may experience:

“This is me.”

Fear appears:

“I am afraid.”

A memory returns:

“My past defines me.”

A mistaken cognition arises:

“What I perceive must be reality.”

These examples can help us contemplate the practical experience of identification. However, Pātañjala Yoga goes deeper than a psychological technique of distancing oneself from thoughts.

It gradually reveals the distinction between the Draṣṭā or Puruṣa and the changing activities of Citta, which belongs to the domain of Prakṛti.

The Pañca Vṛttis must be understood within this wider philosophical framework.

The Five Vrittis

Patañjali states:

वृत्तयः पञ्चतय्यः क्लिष्टाक्लिष्टाः॥१.५॥

Vṛttayaḥ pañcatayyaḥ kliṣṭākliṣṭāḥ

Meaning

“The Vṛttis are fivefold; they may be afflictive or non-afflictive.”

He then names the five Vṛttis:

प्रमाणविपर्ययविकल्पनिद्रास्मृतयः॥१.६॥

Pramāṇa-viparyaya-vikalpa-nidrā-smṛtayaḥ

The five are:

1. Pramāṇa — Valid cognition
2. Viparyaya — False cognition or misconception
3. Vikalpa — Word-dependent conceptual construction without a corresponding object
4. Nidrā — Sleep
5. Smṛti — Memory

An important point is frequently missed in popular explanations of the Yoga Sūtras.

Patañjali does not state that all five Vṛttis are inherently evil or negative.

They may be Kliṣṭa or Akliṣṭa.

In the broader Pātañjala framework, Kliṣṭa is connected with the Kleśas—the afflictive factors later identified as Avidyā, Asmitā, Rāga, Dveṣa, and Abhiniveśa .

A Vṛtti coloured by affliction may contribute to the continuation of bondage and suffering.

An Akliṣṭa Vṛtti is not afflicted in the same manner and may support clarity, discernment, and the Yogic path.

This does not mean that every pleasant or apparently spiritual thought is automatically Akliṣṭa.

The distinction must be understood in relation to affliction and the larger purpose of Yoga.

Therefore, the practitioner should not develop hatred towards Citta.

The first task is to recognise its activities with greater precision.

Are the Five Vrittis Simply Five Types of Thoughts?

Not exactly.

The English word “thought” is often used when explaining Vṛtti, but it can be too narrow.

Consider the five categories.

Pramāṇa concerns valid cognition.

Viparyaya concerns false cognition.

Vikalpa concerns a conceptual construction dependent upon words.

Nidrā—sleep—is also classified as a Vṛtti.

Smṛti concerns the retention of experienced objects.

If Nidrā is a Vṛtti, then Vṛtti clearly cannot mean only a conscious verbal thought moving through the mind.

It is therefore more precise to understand Vṛttis as modes, modifications, operations, or functional activities of Citta .

This distinction is important.

Otherwise, Yoga Sūtra 1.2 is easily reduced to the popular statement:

“Yoga means stopping thoughts.”

Patañjali's analysis of Citta is more sophisticated than this simplification.

1. Pramāṇa: Valid Cognition

Patañjali defines Pramāṇa in Yoga Sūtra 1.7:

प्रत्यक्षानुमानागमाः प्रमाणानि॥१.७॥

Pratyakṣānumānāgamāḥ pramāṇāni

Meaning

“Direct perception, inference, and authoritative testimony are the means of valid cognition.”

Pramāṇa does not simply mean “searching for proof.”

It refers to valid cognition arising through a reliable means of knowing.

Patañjali identifies three forms.

Pratyakṣa: Direct Perception

Pratyakṣa refers to direct perception.

For example, you directly see a flame burning before you.

The flame is directly presented through perception.

However, Pratyakṣa in the classical philosophical context should not be reduced to the statement:

“Whatever I see must be true.”

Perception is analysed more technically within Indian philosophical traditions.

A subjective impression, hallucination, or mistaken perception should not automatically be classified as valid direct cognition.

The distinction between Pramāṇa and Viparyaya itself shows why this caution is necessary.

Anumāna: Inference

Anumāna is inferential cognition.

Suppose you cannot directly see a fire behind a distant hill.

However, you see smoke rising from that area.

On the basis of an understood relationship between smoke and fire, you infer that fire is present.

The fire is not directly perceived.

Knowledge arises through inference from a recognised sign.

Āgama: Authoritative Testimony

Āgama refers to reliable verbal testimony or authoritative communication.

The classical commentarial tradition explains valid testimony in relation to a trustworthy and competent source—an Āpta.

This is an important qualification.

Āgama does not mean that every ancient statement, religious claim, traditional belief, or authoritative-sounding declaration must be accepted as valid knowledge.

The reliability of testimony is connected with the competence and trustworthiness of its source.

Therefore, Āgama should not be confused with blind belief.

Within the Yogic context, reliable teaching transmitted through a competent source can function as a valid means of cognition.

Is Pramāṇa an Obstacle to Yoga?

A common modern interpretation suggests that “too much logic, knowledge, or demand for proof takes us away from Yoga.”

This statement requires serious qualification.

Patañjali does not classify Pramāṇa as inherently wrong.

Yoga Sūtra 1.5 has already stated that Vṛttis may be Kliṣṭa or Akliṣṭa.

Valid cognition can support clarity and discernment.

However, even correct cognition remains a Vṛtti of Citta.

From the perspective of the highest Nirodha, the Yogic journey eventually concerns the stilling of the activities of Citta themselves.

Yoga therefore does not demand irrationality.

It asks us to understand both the function and the limitation of cognition within the larger movement towards liberation.

2. Viparyaya: False Cognition

Patañjali defines Viparyaya:

विपर्ययो मिथ्याज्ञानमतद्रूपप्रतिष्ठम्॥१.८॥

Viparyayo mithyā-jñānam atad-rūpa-pratiṣṭham

Meaning

“Viparyaya is false knowledge not established in the actual nature of the object.”

Viparyaya is false cognition or misconception.

Something is understood as other than what it actually is.

A traditional example is mistaking one object for another under unclear conditions.

A rope may be mistaken for a snake.

The cognition is present.

The fear may be real as an experience.

But the cognition is not established in the actual nature of the object.

The object is a rope.

The mind has apprehended it incorrectly.

A Practical Contemplation on Viparyaya

Viparyaya can also become a useful framework for examining everyday interpretation.

Someone does not reply to your message.

The mind immediately concludes:

“They are angry with me.”

But perhaps the person is busy.

Perhaps the phone is unavailable.

Perhaps there is another explanation.

The event is one thing.

Our interpretation may be another.

When a mistaken cognition is accepted as reality, emotions and actions may begin to develop around an error.

Before reacting, we may ask:

“Do I actually know this, or have I interpreted it?”

This question does not reproduce Patañjali's literal wording.

It is a practical contemplation arising from the concept of Viparyaya.

The distinction matters.

We should not claim that Patañjali was directly discussing unanswered messages or modern cognitive distortions.

Rather, the classical concept can help a modern practitioner examine the accuracy of cognition.

3. Vikalpa: Word-Dependent Conceptual Construction

Patañjali states:

शब्दज्ञानानुपाती वस्तुशून्यो विकल्पः॥१.९॥

Śabda-jñānānupātī vastu-śūnyo vikalpaḥ

Meaning

“Vikalpa is a cognition following from words or verbal knowledge while lacking a corresponding object.”

This definition is more precise than simply translating Vikalpa as “fear,” “daydreaming,” or “imagination.”

Vikalpa is connected with Śabda—word—and the cognition that follows verbal knowledge, while the corresponding object is absent.

The mind can construct a meaningful idea through language even when no corresponding object is actually present.

Words can create conceptual structures.

This capacity is not always useless.

Human beings communicate, reason, imagine possibilities, and engage with abstract concepts through language.

However, Vikalpa may become afflictive when a word-dependent construction dominates our experience and is treated as though it were established reality.

For example:

“I will definitely fail.”

“Everyone will reject me.”

“My future is destroyed.”

The event has not occurred.

Yet the verbal construction may produce genuine fear, agitation, and behavioural consequences.

Strictly speaking, not every future concern should automatically be labelled Vikalpa.

Some concerns may involve Anumāna—inference.

Others may be influenced by Smṛti—memory.

Some may even involve a valid assessment of present evidence.

Therefore, a Yoga practitioner should not mechanically label every imagined future event as Vikalpa.

The practical question is more careful:

“Is this cognition established in an actual object or valid means of knowing, or has a verbal narrative constructed a reality in which Citta has become entangled?”

This is where the concept of Vikalpa becomes deeply relevant to self-observation.

4. Nidrā: Sleep as a Vritti

Patañjali defines Nidrā:

अभावप्रत्ययालम्बना वृत्तिर्निद्रा॥१.१०॥

Abhāva-pratyayālambanā vṛttir nidrā

Meaning

“Sleep is the Vṛtti supported by a cognition or presentation of absence.”

Nidrā is one of the most subtle definitions among the five Vṛttis.

Patañjali does not simply state:

“Sleep is unconsciousness.”

Instead, Nidrā itself is classified as a Vṛtti.

This immediately challenges the idea that Vṛtti means only an ordinary conscious thought.

Nidrā in Vyāsa's Commentary

The Yoga Bhāṣya attributed to Vyāsa, the foundational classical commentary on the Yoga Sūtras, gives important context to the understanding of Nidrā.

The commentary draws attention to the fact that after waking, a person may recollect the quality of sleep.

One may recognise:

“I slept peacefully.”

Another may experience:

“My sleep was disturbed.”

Or there may be a recollection of heaviness or dullness associated with sleep.

This recollection is philosophically significant.

If sleep were understood simply as the total absence of every mental operation in every sense, how could its quality later become an object of recollection?

The commentarial analysis therefore helps explain why Nidrā is included among the Vṛttis of Citta.

Sleep has a cognitive basis associated with absence.

The subject is technically subtle, but the central point is clear:

Patañjali does not exclude sleep from the analysis of Citta's modifications.

Important Clarification: Nidrā and Yoga Nidrā Are Not Identical

Patañjali's Nidrā in Yoga Sūtra 1.10 should not be casually equated with the later systematic practices commonly called Yoga Nidrā.

In Yoga Sūtra 1.10, Nidrā is one of the five Vṛttis.

Yoga Nidrā, as taught in different later Yogic and modern systems, generally refers to structured practices involving deep relaxation and varying degrees of retained awareness.

The history, terminology, and methods associated with Yoga Nidrā require a separate discussion.

Therefore, traditional or modern explanations of Yoga Nidrā should not be presented as though Patañjali himself is teaching the contemporary practice of Yoga Nidrā in Yoga Sūtra 1.10.

Textual precision matters.

5. Smṛti: Memory

Patañjali defines Smṛti:

अनुभूतविषयासम्प्रमोषः स्मृतिः॥१.११॥

Anubhūta-viṣayāsampramoṣaḥ smṛtiḥ

Meaning

“Memory is the non-loss or retention of an experienced object.”

Smṛti should not simply be translated as “living in the past.”

Memory concerns the retention of what has been experienced.

Without memory, ordinary life, learning, language, and disciplined practice would become extremely difficult.

A Yoga practitioner remembers instructions.

A student remembers a teaching.

Previous experience can inform present action because the experienced object has not been entirely lost from Citta.

Therefore, Smṛti is not automatically negative.

Again, the Vṛttis may be Kliṣṭa or Akliṣṭa.

A remembered teaching may support practice and clarity.

A painful memory, on the other hand, may repeatedly become connected with attachment, aversion, or afflictive identification.

An event may have ended many years ago.

Yet its memory may continue to influence present perception and behaviour.

The problem is not simply that memory exists.

The Yogic question concerns our relationship with the Vṛtti.

Is a memory being recognised as a modification arising in Citta?

Or:

Does conformity with the Vṛtti become so complete that the remembered experience appears to define the entirety of who we are?

The distinction between the Draṣṭā and the activities of Citta remains central.

Kliṣṭa and Akliṣṭa: A Crucial Distinction

The words Kliṣṭa and Akliṣṭa are essential to understanding the Pañca Vṛttis.

Kliṣṭa refers to Vṛttis connected with affliction.

Akliṣṭa refers to Vṛttis that are non-afflictive.

Later, Patañjali identifies the five Kleśas:

• Avidyā — Ignorance
• Asmitā — I-am-ness or egoity
• Rāga — Attachment
• Dveṣa — Aversion
• Abhiniveśa — Clinging to life or deeply rooted fear of cessation

The relationship between the Vṛttis and Kleśas is philosophically important.

A Vṛtti coloured by affliction may strengthen patterns that continue bondage.

A non-afflictive Vṛtti may support discernment and the movement towards liberation.

Consider the five categories practically.

Valid cognition may support clarity, yet cognition may also become connected with attachment or egoity.

Memory may preserve a Yogic teaching, or repeatedly reactivate resentment.

Conceptual construction may support communication, or create an imagined reality that generates unnecessary suffering.

Sleep is a natural Vṛtti, yet states of dullness and heaviness may influence practice.

Therefore, the five Vṛttis should not be presented as a simplistic list of “five bad thoughts.”

Patañjali's analysis is more subtle.

The practitioner learns to observe not only what kind of Vṛtti is present, but also how it functions in relation to affliction and the Yogic path .

Does Nirodha Mean Aggressive Suppression of the Vrittis?

The word “suppression” is generally misleading if it suggests an aggressive psychological struggle against thoughts or an attempt to force every mental activity away through violence towards oneself.

Patañjali soon gives the practical framework for Nirodha:

अभ्यासवैराग्याभ्यां तन्निरोधः॥१.१२॥

Abhyāsa-vairāgyābhyāṁ tan-nirodhaḥ

Meaning

“Their Nirodha is through Abhyāsa and Vairāgya.”

The immediate textual answer is significant.

Patañjali does not say:

Fight the mind.

He introduces Abhyāsa—sustained practice—and Vairāgya—dispassion or freedom from thirst towards objects of experience.

Abhyāsa develops steadiness.

Vairāgya weakens the compulsive pull of attachment towards what is seen, heard, or experienced.

Together, they form the immediate practical framework for understanding the Nirodha of the Vṛttis.

This does not mean that the technical meaning of Nirodha can be completely reduced to modern ideas such as “accept your thoughts” or “observe without judgement.”

Those may be useful practices in particular contexts, but they should not automatically be presented as exact translations of Patañjali.

The Pātañjala project is ultimately directed towards a radical stilling of the activities of Citta and the discriminative recognition of the distinction between Puruṣa and Prakṛti.

Practically, however, the recognition of a Vṛtti can begin to weaken automatic conformity with it.

A thought is present.

A memory is arising.

A conceptual construction is occurring.

A mistaken cognition may be operating.

The practitioner begins to observe more carefully.

This observation is not yet the entirety of Nirodha.

But it can become part of the discipline through which the activities of Citta are better understood.

A Practical Contemplation for Yoga Practitioners

The Pañca Vṛttis can become a practical framework for Svādhyāya and self-observation.

When a strong mental activity arises, pause and examine it.

Is this Pramāṇa?

Do I know this through direct perception, valid inference, or reliable testimony?

Is this Viparyaya?

Am I understanding something as other than what it actually is?

Is this Vikalpa?

Has a verbal or conceptual construction created a mental reality without a corresponding object?

What is the quality of Nidrā and dullness?

What is the present condition of Citta?

Is this Smṛti?

Is a retained past experience shaping my present cognition?

These questions are practical contemplations inspired by Patañjali's classification .

They are not direct quotations from the Yoga Sūtras.

This distinction should remain clear.

The purpose is not obsessive self-analysis.

Nor should a practitioner spend every moment anxiously trying to label each mental event.

The purpose is to develop greater clarity about the activities of Citta.

Before understanding the depth of Nirodha, we must begin to recognise what is moving.

The Yogic Purpose of Understanding the Vrittis

The purpose of studying the Pañca Vṛttis is not merely intellectual classification.

Patañjali is establishing the framework through which the practitioner can understand the activities of Citta and the problem of Vṛtti-sārūpya.

Yoga Sūtra 1.4 states:

वृत्तिसारूप्यमितरत्र॥१.४॥

Vṛtti-sārūpyam itaratra

“At other times, there is conformity with the Vṛttis.”

The Pañca Vṛttis are therefore not simply five Sanskrit psychology terms to memorise for an examination.

They describe five broad categories through which the changing activities of Citta can be understood.

Patañjali then gives the immediate practical direction:

Abhyāsa and Vairāgya.

Practice and dispassion.

Āsana and Prāṇāyāma later become important limbs within Patañjali's Aṣṭāṅga Yoga.

Dhāraṇā, Dhyāna, and Samādhi become central to the deeper meditative discipline.

But textual order matters.

Immediately after the discussion of the Vṛttis, Patañjali directs the practitioner towards Abhyāsa and Vairāgya as the means of their Nirodha .

The sequence is philosophically important:

Recognise the activities of Citta.

Understand the problem of conformity with the Vṛttis.

Cultivate Abhyāsa.

Develop Vairāgya.

Move towards Nirodha.

Conclusion

The teaching of the Pañca Vṛttis is one of the foundational elements of Patañjali's analysis of Citta.

Pramāṇa, Viparyaya, Vikalpa, Nidrā, and Smṛti describe five broad categories of Citta's modifications.

Cognition may be valid.

Cognition may be mistaken.

Words may generate a conceptual construction without a corresponding object.

Citta enters the Vṛtti of sleep.

Experienced objects are retained through memory.

Patañjali does not simply declare all mental activity evil.

The Vṛttis may be Kliṣṭa or Akliṣṭa.

The deeper philosophical problem concerns Vṛtti-sārūpya—the conformity of the Seer with the modifications of Citta .

When a modification is present, it can appear to define our entire reality.

A mistaken cognition appears unquestionably true.

A memory appears to define identity.

A conceptual construction appears to be an existing fact.

The study of the Pañca Vṛttis invites the practitioner to examine the activities of Citta with greater precision.

But intellectual classification is only the beginning.

Patañjali immediately points towards the discipline:

Abhyāsa and Vairāgya.

Sustained practice and dispassion.

Through the Yogic path, the relationship with the movements of Citta begins to change.

Know what is moving within Citta.

Recognise the Vṛtti.

Do not automatically mistake every modification for reality—or every movement of Citta for the essential nature of the Seer.

This is where the study of the Pañca Vṛttis begins to move from philosophy into the living discipline of Yoga.
